Abstract
Methods and systems for separating mud from drill cuttings are disclosed. The method includes collecting drill cuttings from a shale shaker or a wellhead, placing the drill cuttings in a fluid that matches the fluid in the drilling mud, and filtering the drill cuttings through a sieve having a first mesh size. The method further includes placing the filtered drill cuttings in a sieve basket having a second mesh size, wherein the second mesh size is smaller than the first mesh size, placing the sieve basket in a vessel, and adding the fluid to completely submerge the drill cuttings in the fluid. The method also includes placing the vessel including the sieve basket, the drill cuttings, and the fluid in a sonicator-shaker, and simultaneously sonicating and shaking the vessel to separate the drill cuttings from contaminants thereon.
